Problem in RegEx cause some mixing between caassets

[niros1]

Problem:
Hashed svg with the following name man.1234566.svg (original file was man.svg) will match icon with this name "cdicon-man.svg" and change it to "cdicon-man.1234566.svg"
Example string: "is.cdicon_man_href=u.a.urls.resources.SVGs+"cdicon-man.svg#cdicon-man",this.authenti"
The reason is the \b does not cover all word boundaries in case of file name ("-" is legible character in file name).

This is the problematic line in the code:
contents = contents.replace(new RegExp('\\b' + original + '(?!\\.)\\b', 'g'), cachebusted);

Suggested regex: [^a-zA-Z0-9_-]man.svg(?!.)\b
Other characters except from "-" can be added
New code line:
contents = contents.replace(new RegExp('[^a-zA-Z0-9_-]' + original + '(?!\.)\b', 'g'), cachebusted);

be glad to get feedback on that, as well I will open a pull request.
